110/100
Answer:
(3x+2)(3x-2)(x-2)
Step-by-step explanation:
1. you do trinomial factoring for the second factor (the one with three terms)
2. you put a 3x in one parentheses and an x in the other and find all the numbers that make positive 4.
3. Now foil (first,outside,inside,last) and see which ones match the factor above
4. You should be left with three factors at the end.
Answer:
Adding the numbers up gives:
2 + 2 + 3 + 5 + 5 + 7 + 8 = 32
There are 7 values, so you divide
the total by 7: 32 ÷ 7 = 4.57...
So the mean is 4.57 (2 d.p.)
Step-by-step explanation:
Answer:
Use the Pythagorean Theorem. Basically, use this equation. a^2 + b^2 = c^2
Note: C = the length of the hypotenuse.
